EYELETING-MACHINE.

SPECIFICATION forming part of Letters Patent No. 368,140, dated August9, 1887.

Application filed December 2, i886. Serial Nn. 220,470. (No model.)

To @ZZ whom it may concern:

Be it known that l, LoENDEn C. EMERsoN,

a citizen of the United States, residing at North Grafton, in the countyof forcester and State of Massachusetts, have invented certain new anduseful Improvements in Eyeleting-Machines, of which the following` is aspecification, reference being had therein to the accompanying d rawing.

My invention relates to that class o f eyeleting-machines which punchthe holes for the eyelets, automatically feed the eyelets to the holesmade Vf'or them and set them therein, and automatically feed the workalong as the eyelets are set; and the principal object of my inventionis to produce an improved machine of the class referred to, capable ofbeing controlled by the operator, so that without stopping the machinethe operation of the eyelet feeding and setting mechanism may besuspended at pleasure to punch holes in the work without setting eyeletstherein. lf desired, the feed of the machine may be increased by thesame movement by which the operation of the eyelet feeding and settingmechanism is suspended, and thus the holes in which no eyelets are setwill be farther apart in the work than the eyeletcd holes. My machine isthus adapted for eyeleting that class of boot or shoe work havinglacing-studs as well as eyelets, the holes punched for the lacing studsbeing preferably a greater distance apart than the eycleted holes.

In the class of machines to which my invention relates the woll; hasheretofore been fed by a horizontally-moving finger, forming a part ofthe eyeletsetting mechanism; but this manner of feedingr the work isobjectionable, particularly with thin goods, as the werk is more or lessstrained and stretched, and such machines are therefore not adapted foreyeleting thin textile fabrics. ln my improved machine l have providedan independent feeding mechanism7 consisting, preferably, of two rockingsegments, between which the work is clamped in feeding, so that thethinnest fabries may be fed without injury. The length of the feed maybe adjusted as may be desired, or the feed may be suspended altogether,to adapt the machine for cyeletin g calendars, &c., vwhere only a singleeyelet is set in each piece of work, and when an automatic feeding ofthe work is not required.

In the drawings, Figures 1 and 2 are elevations from opposite sides ofmy improved ma 55 chine. Fig. 3 is a front end view thereof. Fig. 4 is acentral longitudinal section through the lower part of the machine. Fig.5 is a detail View ofthe cam for operating the slide or carriagecarrying the punch-block and the 6o lower set. Fig. (5 is a crossscctionthrough the upper part of the machine on the line 6 (i, Fig.

1, looking in the direction of the arrows adjacent to said line. Fig. 7.is a rear end view of the upper part of the machine, with the framepartly in section. Fig. 8 is an enlarged detail section of thefeeding-finger and upper set. Fig. 9 is a detail perspective View of thelower or delivery end of the eyelet-chute. Fig. 10 is a detailperspective view of the feeding-sec- 7o tors. Fig. l1A is a sectionalview of the bearing or hanger for the shaft of the upper feedingsectorand adjacent parts. Fig. 12 is a detail sectional view showing the primefeed-operatingshaft, its actuating-cam, and adjacentparts. Figs. 13 and1.4L illustrate a modified form of feeding mechanism. Figs. 1 and 2 areon a somewhat smaller scalc'thau the other figures excepting Fig. 8.

A denotes the frame of the machine, and B So the main or driving shaft,having a drivingpulley, I), mounted loosely thereon, but connectedtherewith by means of the spring-acted dog b', pivoted to a collar,112,'faston said shaft, said dog being normally forced into yengage- S5ment with a notch in a flange, b, of the wheel b by a coil-spring, b",seated in a recess in said collar. (See Fig. 4t.)

O is a rock-shaft mounted in the lower part of the frame A, and providedat one end with 9o a tripping-arm, c, adapted to disengagc the dog bfrom the notched flange of thc wheel I), said shaft having also an arm,c', which is to be connected with a suitable treadlc to operate theshaft C, for the purpose of disengaging the clutching-dog Z/from thewheel b, and thus stop the machine. This clutching mechanism is,however, of itself old and not of my invention.

Journaled in the lower part of the frame A, Ico in line with thedrivinglshaft B, is a secondary shaft, D, having a clutch-connectionwith said erated from the driving-shaft B, while the eyelet feeding andsetting mechanisms are opere.

ated from the secondary shaft D, so that when the shaft D isdisconnected from the shaft B the operation of the eyelet mechanisms,which I willnow first describe, will be suspended.

E is a slide or carriage having dovetailed iianges e, by which it isguided in ways formed by the under cut plates a, secured to the frontend of thelower part of the frame A, said slideor carriagehavingastandard, E', through which slides vertically the bar e',carrying the setting-finger or Vlower set, e2. ,To the said standard isattached a post, 10, carrying the punch block 11. rlhe slide E isreciprocated horizontally by means of a rock-shaft, F, having at itsrear end an ar1n,f, provided with a pin or roller engaging a cam-groove,g, in the disk G, secured to the shaft D, the said rockshaft F having atitsL forward end a slotted arm, f', engaging an adjustable bolt, c",attached to the slide E. By adjusting the bolt e3 so that it will benearer to or farther from thevcenterof movement of the shaft F the throwof the slide E may be varied as desired.

To the sliding bar c is attached a collar, e, which is connected by alink or pitman, e5, with the crank-disk d at the forward end of theshaft D, so that as the said shaft rotates the said bar will bereciproeated vertically to canse the set carried thereby to cooperatewith the upper set in setting the eyelets.

H is a rock-shaftjournaled in lugs or hangers va?, formed on the upperpart of the frame l, A, said shaft having at its re'ar end an arm, h,

connected by a pitman, 7L', with an eccentric, H', carried by the shaftD. At the forward end of the'shaft His an arm, h1, connected by a link,h, with a bar, h, sliding vertically in bearings formed in flanges 'L'of a head, I, pivotally attached by a screw-bolt, i, to the `forward endof the upper part of the frame A. The sliding bar h carries the upperset, h4, which is in the present instance adjustably attached to thesaid bar by the fasteningscrew 71.5, the said set being guided by thelower flange of the head I, so that it will move steadily with the saidhead as the latter swings.`

J is a stationary eyelet-box having a stationary roadway or chute, j,down which the eyelets pass to the eyelet-feeding linger h, whichreciprocates vertically in the upperset, h rIhe said finger 71. isprovided nearits lower end with a friction-spring, h1, (see enlargeddetail view, Fig. 8,) which serves to'retain the eyelets thereon whilethe said finger is movingfromthelower end ofthestationary eyein theswinging head I. Thus, as the upper set rises, the finger h6 will beprotruded therefrom, owing to the contact of the upper end of its shankwith the rod i2. 'Ihe swinging movement of thc head I will neXt bringthe said finger over the delivery end of the chute j, and before thesaid head commences its return movement the bar h3 will have descendedfar enough to cause the said finger to take an eyelet from the lower endof the chute, and the continued movement of the said head brings theeyelet-finger and upper set over the hole in the work, into which theeyeletis inserted as the upper set and eyelet-nger descend, the lowerset being at this time beneath saidy hole. The contact of theeyelet-nger with the lower set forces said finger up into the uppersct,Whereitisretained by the spring hs until again forced outward by the rodi2. The eyelet-chutej is provided atitslower end with aretaining-spring, j', which extends l tating-brush, operated in theusual manner Vfrom the arm 719 on the rock-shaft II, said arm beingconnected by a link, ji, tothe arm ofthe brushshaft. y

The swinging head I is operated in one direction by a rock-shaft, K,having at its forward end an arm, 7c, carrying a pin or roller engaginga grooved block, i# on the head I, or to a plate attached thereto. Theshaft K is provided at its rear end with an arm, K', having aroller-stud, k2, which at proper intervals is engaged by a cam ortappet, It, secured to the shaft H. The return movements ofthe head Iand of the rock-shaft K are effectedby a coilspring, L, attached to saidhead and to a block or projection, a5, ou the frame A. An adjustablescrew-stop, a, tapped in the block a5, limits the return movements ofthe head I. To prevent the said head from overthrowing I also prefer toemploy a stopscrew, al, tapped in a block or projection, as, on theframe A. The punch 12 is carried by avertically-reciprocating bar, I3,having bearings in the flanges of the swinging head I, the said punchbeing steadied by passing through the lower one of thc said fianges, asis the upper set, 7L". rIhe bar 13 is connected by a link, 14, with anarm, 15, on the forward end of a rockshaft, 16, the rear end, 17, ofwhich is connected by a pitman, 18, with the strap 19 of an eccentric,20, fast on the drivingshaft B, so that as the said shaft rotates thepunch will be reciprocated to perform its work.

The feeding mechanism which I prefer to employ consists of twooscillating sectors, M and M', between which the work is clamped duringthe feeding movement, the upper sector rising to unclamp V the work whenthe sectors swing backward, the said sectors being slotted to embracethe work on both sides of the punching and eyeleting devices, which canwork through the slots of the sectors.

IOO

The upper sector, M, is formed on an arm, m, of a stud or smallrock-shaft, m,journaled in a hanger or bearing, o, carried by avertically-movable bar, O, extending through the upper part of the frameA and having near its top a pin, o', engaged by lifting-lever Q. Theshaft m is provided at its rear end with an arm, m, connected by a link,m, with an arm, n, of a rock-shaft, N, having at its rear a second arm,a', connected by a pitman, ai, with an arm, p, of a short rock-shaft orstud, P, having within the frame A an arm, p carry: ing a roller-studengaging the grooved cam R on the driving-shaft B. The lower sector, M',is carried by the arm s of a rock-shaft, S, the forward end of which isjournaled in a standard, T, to which is attached the work-plate t, thearm s on the rear end of said shaftS being connected by a link, 8"',with an arm, a3, on the rock-shaft N, from which the upper seetor, M, isoperated, and thus the sectors will be caused to move in unison. -Thelever Q, by which the bar O is lifted to raise the sector M and unclarnpthe work, is connected at its rear end with the pitman 1S by a rod, q,having adjusting and set nuts q and g2, and the downward movements ofthe said bar and the parts supported thereby are effected by a spring,V, pressing on the bearing o, the latter being provided with a stud, o2,entering a hole in the frame A and serving to prevent torsional movementof the bar O.

The pitman a* is preferably made adjustable in length by being formed intwo parts, the adjacent ends of which are threaded to tit within a rightand left hand threaded sleeve, as, which may be turned to lengthen orshorten the said pitman. rlhe latter is jointed at its upper end to aloop, n, adapted to slide on the arm nef the rock-shaft N, the said loopbeing held between adj ust-able collars as, theposition of which on thearm a may be changed to vary the point of connection (through the loopa) of the pitman at with the said arm a to v ary the rocking movement ofthe said shaft N, and thus adjust the normal throw of the feedingsectorsoperated therefrom. The pitman n2 is also provided at its lower end withajointed loop or collar, a, adapted to slide on the arm p of the stud orroekshaft P, the said loop a being connected by a link, w, with an arm,w", carried by a collar, lw, on a rock-shaft, \V, and the said shaftbeing provided with an ordinary forked arm, 102, engaging aslidingcollar, X, splincd t-o the driving shaft B. The eccentric ll', which ison the shaft D, is provided with a pin, 2l, adapted to fit a hole in thesliding collar X, so that the driving-shaft B and the secondary shaft Dmay be connected or disconnected by moving the said collar into or outof engagement with the said pin, the latter and the collar with theholeto receive said pin thus forming a clutch by which the shafts B andD may be coupled together. rlhe cellar w is provided with a second arm,w, which will in practice be connected with a suitable treadle tooperate the clutch fork or arm wg.

As the loop a" is connected by the link w, arm w", and collar w with therock-shaft XV the movement of thelatter in unclutching the secondaryshaft D (from which the eyelet feed ing and setting mechanisms areoperated) from the driving-shaft B will cause the said loop to slideoutward on the arm of the prime feedoperating rock-shaft P, and thus agreater reciprocating movement willbe imparted to the pitman aL to givean increased rocking move ment to the shaft N,and also the rock-shaft Sconnected therewith, so that the movement of the rock-shaft XV innnclutching or disconnecting the secondary shaft from the driving-shaftto suspend the operation of the eyelet feeding and setting mechanismswill also give au increased throw to the feeding-sectors, and thus spacethe non-eyeleted holes farther apart than the eyeleted ones.

The outward movement ofthe loop Wat the lower end of the pitman Mou thearm p of the rock'shaft P is limited by an adjustable stop, consistingin the present instance of a collar, p2, Fig. 2, held in place ou saidarm by a setscrew.

'Vhen my machine is set in motion, its operation is as follows: Thepunehl2, receiving its motion from the rock-shaft 15, operatively connectedwith the eccentric 2O in the driving-shaft ]3,first descends and makes ahole in the work, the punelrbloek l1 being at this moment beneath thepunch. As the punch rises, the punch-block, carried by the slide orcarriage ll, moves backward or to the right, Fig. 3, thus removing thepunch-block from beneath the hole which has been made in the work andbringing the lower set, 6"', beneath the said hole. The punch as itrises is (owing to the swinging of the head f, in which it has verticalbearings) carried to the left, Fig.A 3, this movement of the said headbringing the descending upper set, 7L", in a vertical line with the holein the material and the lower set, 6". During the down ward and forwardmovement of the upper set, h, the eyelet-feeding finger h carriedthereby has taken an eyelet from the eyelet-chutej, and as theupper setcontinues i't-s downward movement {the lower set meanwhile rising) theeyelet is inserted in the hole made for it by the punch and properlyset, the eyelet-feeding finger being forced within the set h during thesetting operation and protruded therefrom, when the set again rises bythe rod on the head l, as hereinbefore described. As the upper setrises, the return movement oftheswingingheadI carriesitback` ward (or tothe right, Fig. 3,) thus bringing the punch to its firstposition,theslide or carriage E at the same time moving forward,(or tothe left, Fig. 3,) to carry the lower set (which has meanwhiledescended) away from beneath the punch and to bring the punch -blockback again into operative position. After the two sets have beenwithdrawn from the work and before the punch again reaches it, thefeeding sectors M and M, between which the work is now clamped, andwhich are operated by the IOO los

IIO

ISO

4 v fesant mechanism hereinbefore described, swing to feed the workforward (or to the left, Fig. 3,) and as the punch reaches the work theupper sector, M,is raised through the operation of the lifting-lever Q,to release the work, and while the work is thus unclamped thefeedingscctors'are swung backward to their trst position.

The movements above described are repeated during the usual operation ofthe niachine in punching holes and setting eyelets therein; but when theproper number of eyeletshave been set iu a shoe-counter, and it isdesired, without stopping the machine, to punch a series of holes forstuds andto space the said holes farther apart than the eyeleted holes,the operator presses down 'on a treadle which is to be connected withthe arming', rigidly connected with the clutch-operatingrockshaft W, toslide the collar X rearward, and thus'uncou'ple the secondaryshaft D,bywhich the eyelet feeding and setting mechanism, the sliding carriage E,and the swinging head I are operated, from the driving-shaft B,fromwhich the punching and feeding mechanisms receive their movements,and thus the latter mechanisms will continue their operation to makeproperly-spaced holes in which no eyelets will be inserted. `Owing tothe Iconnection by thelink w of theloop n at the lower end of thefeed-operating pitman n2 to the arm w, moving with the clutch-operatingrock-shaft WV, the lower end of the said pitman will be moved outwardrelative to the arm j) of the prime yfeed-operating shaft Psimultaneously with the uncoupling of the shafts D and B, to increasethe feed when the holes in whichno eyelets are to be inserted are beingpunched, as hereinbefore described, this movement of the lowerend of thesaid pitman being reversed to restore the normal feed when the saidshafts are again coupled together to resume the eyeleting operations.

It will be observed that the lower end of the eyelctchutej is above thework-plate t, and owing to the form of said chute the eyelets, when theyreach the lower end thereof, have their fianged or finished ends upward,so that the eyeleting operation is performedwith the right or outer sideof the work upward. This enables the operator to inspect the Work as theeyeleting and punching operations proceed and to sce if there are anybad places therein, and my machine will therefore be found moreconvenient in use than the combination eyeleting-machines heretoforeextensively employed. The retaining-spiinghi, near the end of thecyelet-feeding finger 7L, is an'important feature of my -invention incarrying the eyelets from the stationary chute to the holes in the workpunched for their reception and inserting them in the holes vfrom abovethe work. When the operation of the cyelet feeding and setting devicesare sus' pended,the sliding movements of the carriage E and the swingingmovements of the head I are also suspended, these movements belngimparted to the said slide and carriage from the rock-shafts F and K,operated from the secondary shaft D, as hereinbefore described, so thatwhen the punching operation goes on Without the eyeleting operation thepunchblock remains stationary beneath the punch, and the latter merelyreciproeates vertically in the head I, which latter remains at restuntil the eyeleting operation is resumed. l

If it be desired to punch holes alone or topunch eyelet-holcs in workwhere no feed is necessary, owing to the fact that only a single hole oreyelet is required in each piece, as in eyeleting calendars, Snc., thefeeding devices may be disconnected from their operating mechanism, asby removing the pitman n2,- or the said pitman may be adjusted on thearm a so closely to the center of movement of the shaft N that little orno movement will be imparted to the said shaft, and thus thefeedingsectors operated therefrom will be entirely or practically atrest. When the feed is thus suspended,the sector M may be raised so asto be clear of the work by an ordinary lifting-lever engaging the`bar Oor the lever Q, and, if desired, the feed may be suspended simply byraising theV upper sector from the work and retaining it in suchposition; but power will be saved by disconnecting the rod n2.

By employing an independent feeding mechanism, or a feeding mechanismwhich operates independently of the eyelct-setting devices, my machineis adapted for setting eyelets in thin materials,which are more or lessinjured when fed by the setting devices,

IOO

as in the forms of eyeleting-machines now in ing of two feeding-wheels,M2 andMS,the shaft m of the upper wheel, M, being intermittingly rotatedby the ratchct-wheel m", operated by the pawl m5, pivoted to the carrierm, operated from the rock-shaft `N through the link m and arm a, thelower wheel, M, rotating idly by the movement of the work between it andthe upper wheel. These feeding-Wheels are in a certain sense theequivalents of the feeding-sectors M M', in that they adord twocoincidently-moviug surfaces between which the work is clamped infeeding.

I donot, therefore, wish to be understood as limiting myinvention to thespecific operating mechanisms hereinbefore described, as it is obviousthat the details of my machine may be varied within the limits ofmechanical skill without departing from the leading features Y chine isadapted for a much larger range of work than the old machines.
